How aptly named is the word ‘grog’? A popular relaxant and Australian social icon, I admit to availing myself of a few cool ales over the summer break in a good communal spirit. The only thing is, it tends to leave the headlights a bit ‘foggy’ and the antennae a bit less sharp, doesn’t it. To have a relaxed, joyful, wound-down heart is good thing: but a dulled and foggy headspace - not so much.
